, To all whom it my cof/wcm: 'edges of the trent and rear movement-plates Beit known that l, FREDERICK WEHINGER, l12 andl 13. The lower face of 'the said wind-'3 a citizen of the l'United States, residing at ing-pinion 10 is formed with a face-ratchet x Waterbury, in the county of .New Haven and 14 forming one member of ha clutclnthe other State of Connecticut, have invented a new member of which consists oa corresponding 6o. and useful Improvement in Winding Mechf face-ratchet l5 orneill upon the upper face l anism for Watches; and I do hereby declare of a collar 16 having a square opening and the following, when taken in connection with mounted upon the squared lower .end of a y,the accompanying drawings and the characshort shaft 17 the extreme lower end` of ters of reference marked thereon, to be a which is engaged by 'a spring l8 exerting a 65 ful-l, clear, and exact description of the same, constant e'ort to push the shaft outward.4 and which said drawings constitute part of The said shaftl? passes through the windthis application, and represent, in ing-pinion .10 and has longitudinal and ro.y .Figure l a plan view of a watch-movetary morement,its outer endbeing furnished i ment constructed in accordance with my 1n-4 with asetting pinion 19 the lhub 20`thereof-7o vention.

Fig. 6 la view in horizontal bridge 2, itis essenti l to split the bridge by section on the line ab o Fig. 1.

Fig. 8 a broken view in vertical Vto be inserted into the circular barrelbpensection'on the line c-d of Fig. 1. ing 3 from the inside of the bridge 2. After My invention relates to an improved windvthis has been 4lone, the bridge Q'springs to ing mechanism for watches, the object being gether so as to hold the barrel 5 as shown in' 85 to Jrovide at all times a support of superior Fig. 7. The bridge is prevented from.

As shown, the rear enc said opening receives the main-,spring barrel of the' arbor 27 is formed with a shoulder 29 5 which is :formed upon its back 6 with a1 to lreduce the friction between the Jmain- 1,00 beveled over-hanging annular bearing-flange arbor and the barrel over what thel frictiony 7 adapted to bear upon the barrel-bearing 4: ,'would be ifthe full diameter of the main*- of the bridge, as clearly shown vin Fig. 7. arbor bore upon the inner face of the-backl The said barrel 5 is provided, as usual, with 6 oi the barrel. The front end f the maincircumferential teeth S located directly below arbor 27 is formed with a trungion 30 hav-' 105 the overhanging bearing-flange 7 an meshing bearing vin an opening 3l in the front ing into 'an intermediate winding-pinion 9 movement-plate 13. Upon the ma1n-arbor mounted upon the said bridge 2, and-in turn 27 l mount the main wheel S2 wl'nchmeshes meshing into a winding-pinion 10 mounted into the center pinion, not shown, of t e' in a bridgell supported between the upper watch. f The main arbor Q7 is providedd as 11G usuahrwith a hook S3 for the inner end of 2. In a Watch movement, the combination the main-spring 34 the outer end of which Wlth a barrel bridge having a circular bari q shown the teeth 8 -place by for th hook upon the inner rel-opening, of a normally-stationary barrel as s'ho'vv'nin F ig. 7. AS1 located in the said barrel opening of the of the barrel 5-are e11- bridge and bearing at its edge directly upon Winding l the bridge in vvhich it is rotatable for the Winding of the spring, tating mainfspring arbor the rear end of which is journaled directly in the center of the back of the said barrel.` p

3. In a Watch movement, themembination with the front and rear movement plates thickness of the bridge itself. At the same thereof, of a bridge adapted to be applied to timev a stable support is secured for the i the said rear movement-plate and formed main-spring barrel 2 on account of the great I with a split barrel-opening, a barrel adapted diameter ofthe bearing and the dovetail to be set into the said barrel-opening and characterof the mounting'of the barrel in the bridge in which the barrel turns when the spring is being woundbut, of course, at no other time.

I claim:` ,l 1In a Watch, the combination with al bridge having a split barrel-opening formed I with a beveled annular barrel-bearing, of a g l is engaged-With a face of the barrel gaged by the nose of a recoiling, pawl 36 operated by a spring 37, and held in a stud 38 upon the inner face of the back movement plate l2.

By utilizing the bridge 2 as a bearing emain-spring barrel 5, the thickness of the movement may be reduced by the full the barrel is rotated for the purpose of winding the spring, and a main-arbor jourg naled at its rear end directly in the oenter of the back of the barrel and Having its front end journaled in the front movementplate of the Watch.

In testimony whereof, I have signed this specification in the presence of tWo sub- 1 scribing Witnesses.
